Thanks, Joe. For the fourth quarter of 2020, we incurred a net loss attributable to Valero stockholders of $359 million, or $0.88 per share compared to net income of $1.1 billion, or $2.58 per share for the fourth quarter of 2019. The fourth quarter 2020 adjusted net loss attributable to Valero stockholders was $429 million, or $1.06 per share compared to adjusted net income of $873 million, or $2.13 per share for the fourth quarter of 2019. For 2020, the net loss attributable to Valero stockholders was $1.4 billion, or $3.50 per share compared to net income of $2.4 billion, or $5.84 per share in 2019. The 2020 adjusted net loss attributable to Valero stockholders was $1.3 billion, or $3.12 per share compared to adjusted net income of $2.4 billion, or $5.70 per share in 2019. Fourth quarter and full-year 2019 and 2020 adjusted results exclude items reflected in the financial tables that accompany the earnings release. For reconciliations of actual to adjusted amounts, please refer to those financial tables. The refining segment reported an operating loss of $377 million in the fourth quarter of 2020 compared to operating income of $1.4 billion in the fourth quarter of 2019. Excluding the LIFO liquidation adjustment and other operating expenses, the fourth quarter 2020 adjusted operating loss for the refining segment was $476 million. Fourth quarter 2020 results were impacted by narrow crude oil differentials, lower product demand and lower prices as a result of the COVID-19 pandemic. Refining throughput volumes averaged $2.6 million barrels per day, which was lower than the fourth quarter of 2019 due to lower product demand. Throughput capacity utilization was 81% in the fourth quarter of 2020. Refining cash operating expenses of $4.40 per barrel were in line with guidance with $0.47 per barrel higher than the fourth quarter of 2019, primarily due to the effect of lower throughput rates. Operating income for the renewable diesel segment was $127 million for the fourth quarter of 2020 compared to $541 million in the fourth quarter of 2019. After adjusting for the retroactive blender's tax credit in 2019, adjusted renewable diesel operating income was $187 million in the fourth quarter of 2019. Renewable diesel sales volumes averaged 618,000 gallons per day in the fourth quarter of 2020, a decrease of 226,000 gallons per day versus the fourth quarter of 2019 due to the effect of planned maintenance. The segment set annual records for sales volumes of 787,000 gallons per day and margin of $2.66 per gallon. Operating income for the ethanol segment was $15 million in the fourth quarter of 2020 compared to $36 million in the fourth quarter of 2019. Ethanol production volumes averaged 4.1 million gallons per day in the fourth quarter of 2020, which was 197,000 gallons per day lower than the fourth quarter of 2019. The decrease in operating income from the fourth quarter of 2019 was primarily due to lower margins, resulting from higher corn prices and lower ethanol prices. For the fourth quarter of 2020, G&A expenses were $224 million and net interest expense was $153 million. G&A expenses in 2020 of $756 million were $112 million lower than 2019. Depreciation and amortization expense was $577 million and income tax benefit was $289 million in the fourth quarter of 2020. The annual effective of tax rate was 45% for 2020, which was primarily the result of the carryback of our U.S. federal tax net operating loss to 2015 when the statutory tax rate was 35%. And we expect to receive a cash tax refund of approximately $1 billion in the second quarter of this year. Net cash provided by operating activities was $96 million in the fourth quarter of 2020. Excluding the unfavorable impact from the changes in working capital of $113 million and our joint venture partner’s 50% share of Diamond Green Diesel's net cash provided by operating activities, excluding changes in DGD's working capital, adjusted net cash provided by operating activities was $140 million, and adjusted net cash provided by operating activities was $955 million for the full year. With regard to investing activities, we made $622 million of total capital investments in the fourth quarter of 2020, of which $214 million was for sustaining the business, including costs for turnarounds, catalysts, and regulatory compliance, and $408 million was for growing the business. Excluding capital investments attributable to our partner’s 50% share of Diamond Green Diesel and those related to other variable interest entities, capital investments attributable to Valero were $458 million in the fourth quarter of 2020 and $2 billion for the full year. Moving to financing activities, we returned $400 million to our stockholders in the fourth quarter of 2022 through our dividend and $1.8 billion through dividends and buybacks in the year, resulting in a total 2020 payout ratio of 184% of adjusted net cash provided by operating activities. And our Board of Directors just approved a regular quarterly dividend of $0.98 per share, demonstrating our strong financial position and commitment to return cash to our investors. With regard to our balance sheet at quarter-end, total debt and finance lease obligations were $14.7 billion and cash and cash equivalents were $3.3 billion. The debt to capitalization ratio net of cash and cash equivalents was 37%. And at the end of December, we had $5.9 billion of available liquidity, excluding cash. Turning to guidance, we expect capital investments attributable to Valero for 2021 to be approximately $2 billion, which includes expenditures for turnarounds, catalysts and joint venture investments. About 60% of our capital investments is allocated to sustaining the business and 40% to growth. Almost half of our growth CapEx in 2021 is allocated to expanding our renewable diesel business. For modeling our first quarter operations, we expect refining throughput volumes to fall within the following ranges, Gulf Coast at 1.49 million to 1.54 million barrels per day; Mid-Continent at 410,000 to 430,000 barrels per day; West Coast at 170,000 to 190,000 barrels per day; and North Atlantic at 245,000 to 265,000 barrels per day. We expect refining cash operating expenses in the first quarter to be approximately $4.75 per barrel, which is impacted by lower throughput volumes due to planned maintenance activity. With respect to the renewable diesel segment, we expect sales volumes to be 790,000 gallons per day in 2021. Operating expenses in 2021 should be $0.50 per gallon, which includes $0.15 per gallon for noncash costs such as depreciation and amortization. Our ethanol segment is expected to produce 3.7 million gallons per day in the first quarter. Operating expenses should average $0.39 per gallon, which includes $0.06 per gallon for noncash costs, such as depreciation and amortization. For the first quarter, net interest expense should be about $155 million, and total depreciation and amortization expense should be approximately $575 million. For 2021, we expect G&A expenses, excluding corporate depreciation to be approximately $850 million, and the annual effective tax rate should approximate the U.S. statutory rate. That concludes our opening remarks. Before we open the call to questions, we again respectfully request that callers adhere to our protocol of limiting each turn in the Q&A to two questions. If you have more than two questions, please rejoin the queue as time permits. And please respect this request to ensure other callers have time to ask their questions.
